(01.220-1) The present invention relates to a mixing device for obtaining bycentrifuging comestible liquid or semi-liquid mixtures and combinations,said device being based on a receptacle for containing the substances tobe mixed or combined and is characterized by a separable coupling devicefor coupling said receptacle to a supporting column provided with meansfor fixing the same to any supporting base. An essential object of thisinvention is to provide a device of the class referred to whichcomprises a mechanical com bination of elements arranged in mutuallycooperative relationship to provide a manually operable driving assemblyfor a vertical shaft carrying the stirring means for the substancescontained in the receptacle. Said driving assembly comprises a train ofgears which includes a toothed wheel fast on a manually operable shaft,said wheel meshing with a pinion fast on a shaft manually operableindependently of the shaft of said toothed wheel. Said pinion isintegral with a step-up gear wheel meshing with the pinion of a verticalshaft to which are separately and interchangeably connected the shaftscarrying the stirring members for the substances to be subjected to theaction of said members, said gear train forming a means whereby an axialrotary motion is transmitted to the shafts carrying the stirringmembers, at two speeds, one of which is accelerated by the action of theshaft carrying the toothed wheel meshing with the pinion associated withthe second shaft. said pinion together with the gear wheel integraltherewith its the highspeed rotary motion transmitting unit to thepinion integral with the shaft transmitting the axial rotary motion tothe stirring members. lhe second slower rotary motion is provided by thesecond shaft the gear wheel of which causes rotation of the pinion faston the shaft carrying the interchangeable stirring members.

The apparatus assembly is complemented by other constructional andfunctional features to be hereinafter described in accordance with theaccompanying drawings in which a practical embodiment is illustrated byway of example, wherein:

Figure l is an elevation of the apparatus assembly with parts thereof insection,

Figure 2 is a plan View illustrating the assembly in cross-section alongthe line A--A of Figure 1, and

Figures 3, 4 and 5 illustrate the respective shafts carrying thestirring members consisting of a liquifying mixing and beating unit.

in the figures the same reference numbers and.

letters are used to indicate similar or corresponding parts.

In the embodiment shown in the drawings the device according to thepresent invention comprises a receptacle 04 consisting of a hollow bodyof irregular lateral shape having curved portions as at 2 extendingradially inwardly and forming internal ribs 2. These ribs as may beappreciated assist in obtaining a complete agitation of the contents ofreceptacle a which, near the mouth thereof has embedded therein a ring 3adapted to allow a hook portion d of a hooked arm to be insertedthereunder. Hooked arm 5 is integral with a supporting column b andserves to support receptacle a. At a certain distance from hooked arm 5there is provided on column b a projection t (Figure l) whichconstitutes a lateral steadying member for receptacle a and acts tomaintain the same in a proper vertical posi tion and parallel to columnb. Near the lower end of column b and integral therewith there isprovided a clamping device consisting of forked member arranged oppositea plate ii. Passing through plate 8 there is provided a screw 9 operableby means of a wing nut it or any equivalent element and that end ofscrew 9 between fork member l and plate d has fast thereon a conicalwasher Ii. The clamping device as may be seen is provided for fixing themixer in a suitable position on a table or the like.

At one end of column b there is provided a widened head portion forminga casing 52 within which a driving pinion i3 is mounted for rotation.Pinion it is fastened to the upper end of a driving shaft it guided in aboss it which. depends from the lower surface of the aforementionedcasing. Shaft it extends transversally of said casing and has securedthereto a sleeve is constituting a coupling shaft Hi and the stirringelements which will be described hereinafter.

Pinion l3 meshes with a step-up gear is secured on a vertical shaft asto which is also fastened a toothed pinion 2d. Shaft it extends rthrough the outer wall of a recess formed in a cover plate 22 of casingl2 and constitutes a handle receiving portion 23 for handle 2d. Toothedpinion 2E meshes with a step-up gear i5 secured to a shaft 26 mountedfor rotation on coverplate 22 and extending through recess 2| to providea handle receiving portion 2'! similar to that previously described.Handle 24 may be removably mounted on either portion 23 or portion 2! ofshafts l9 and 26 respectively as desired or required.

Sleeve I6 is provided with a bore 29 into which driving shaft [4 iskeyed and to the lower end of this shaft there is secured one end of ahelical expansion spring 30 whilst the other end of said spring bearsagainst the upper end of a vertical shaft 3| which projects into saidbore and is provided with a pin 32 for coupling the shaft to the lowerportion of sleeve l6 which for this purpose is provided withcorresponding slots into which the ends of pin 32 are inserted whenshaft 3| is in the correct angular position. To the lower end of shaft3| there is secured a' stirring; plate 33 of hexagonal shape.

The apparatus also comprises two further shafts 34 and 35 to the lowerends ofwhich are secured, respectively, blades 36 having a cutting edge3! for slicing, when necessary, solidly'placed in receptacle a and a setof rings 38 normally fixed so as to form a whipping unit. Blades 36constitute a liquifying unit and the respective ends thereof extendobliquely one with respectto the other, the arrangement being such thatit is possible to achieve a high degree-of efliciency in the liquifyingprocess.

Although in the foregoing description reference has been made toliquifying, mixing and whipping units each fixed to an individual shaftit will be understood that the arrangement may be such that these unitscan be rem'ovably and interchangeably attached to one single shaft. Inthis case, upon conclusion of the mixingior' combining process, theinterchange of the whipping and mixing units on the shaft may beeffected without the necessity of removing shaft 3| from coupling sleeve|9 it being evident that only r ceptacle arequires removal.

The mixer operates as follows: once the receptacle a has been placedinposition on column b and charged with the substances to be treatedrotation of the blades at accelerated speed may be produced by placinghandle 24 on handle-receiving portion 2! of shaft 26 and rotationthereof will cause the step-up gear 25 to rotate and the latter willtransmit its movement to pinion and hence to step-up gear l8 which isin"- tegral with pinion 2D. The accelerated movement of gear l8 istransmitted to pinion l3 fast on shaft M to which shaft 34' or3l iscoupled as the case may be.

For whipping which requires rotation at a lower speed it is sufiicientto place handle 24' on handle-receiving portion 23 of shaft |9 wherebythe multiplication of speed through theaction of gear is eliminated.

It will be understood that while a preferred embodiment of the inventionhas been described,

many modifications and variations may be introduced in the structuraldetails without departing from the scope of the invention as defined inthe annexed claims.
